T0 all whom, t may concern,.- y

Be it known th at LJoNATHAN DMAXWELL,

a citizenl of the United States of America, residing at Detroit, in the county'of Wayne and State of Michigan, have invented certain new and usefull-m provements in-M'otor-Vehicles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates more specifically to improvements in the'running-gear of motorvehicles of the type of the automobile driven by gasolene or other gas, vapor, or steam engine and in. which the bodyland'motor are supported upon springs.

Myinvention is designed with the general object in View to make-an efficient runninggear composed of fewand simple parts specifically adapted for the commercial manufacture on a large scale, while at the same timev an easy and comfortable riding vehicle of' pleasing appearance and moderate V,cost is produced.

To this end my invention embracesseveral spec'c features, one of 'which relates to the support `of the body, whereby the jar or vi-Q bration of the engine, which is so particularly noticeablein the use of the gasolene and va-` por engines, is prevented from lbeing transmitted tothe body. Another feature relates to the Vmountingof the motor, wherebyv its frame is madek a structural partof the run-e ning-gear and at the same time aordsgreatVA facility forthealinement.` g

The invention also has reference to a novelA construction of axle-clips for connecting the springs to the axles, alias more fully herein of the axle-clip shown in Figs. 4 and 5 in detached views. Figs. 9 and 10 are vertical longitudinal sections of the front and rear axleclips for fastening the side springs to the front and rearfaxle, respectively. Fig. 11 is a plan Fig. 12 is an end elevation of Fig. ,10i Fig. 13 is a 'perspective view of a view of Fig. 9.

part'of Fig. l0 detached. Fig.v .14 is a horizontal section of the part which pivotally connects the body with the side springs. Fig. 15 is a perspective view ofthe part shown in Fig. 14.-,

and Fig.. 16 is an elevation of the loop through which theA chain passes in the `bar J'.

A is the front axle,` B represents stubaxles pivotally 'secured to the front axle, C.

represents the steering-arms'connecting the stub-axles with the steering-gear, D` represents the front wheels, E is'the rear axle, in which the drive-shafts for the rear wheels are journaled, F represents the rear wheels, secured t'o the drive-shafts, and Gis the rearaxle casing, inclosing the usual compensating .gearfwhich transmits the motion from the motor-shaft through the sprocket-chain H to the rear drive-wheels, all arranged and operating in a well-known manner.

" lI I are two side springs, the ends of which are rigidlyA secured to the front and rear axles,respectively,to form a connecting-reach. `.Theseside springs may be of the semi-elliptic kind in common use, or, as will be more desirable, they are made with a'level body portion which iscomparatively rigid and with inclinedfront and rear portions, the vlatter being shorter and more inclined than the-front portions, as they will have to bear the greater load.2 V

J J are two bars, tubes,-or rods transversely connecting the side springs at or near the ends offtheir level body portions', and theends of these rods are suitably secured to the springs vinany manner that Willpermit of their independent adjustment. bearing-plates K, resting on top of the springs and secured thereto by U-shaped clamping-- To thisend I provide,

IOC

which the rods .I J pass and upon which the frame of the motor is clamped, all in such manner that the motor is thereby supported in a horizontal position in the longitudinal line of the vehicle.

The crank-shaft R of the motor extends laterally toward one of the side springs and is supported thereupon by an end bearing g. It carries the usual balance-wheel R and the drive-pinion S, which transmits the motion through a chain II to the rear wheels. This chain passes through a guard loop or eye h, formed in the bar J', as more particularly shown in Fig. 16.

The body L is pivotally supported upon each of the side springs by means of pivotal side bearings, particularly shown in Figs. 14 and 15, and consisting of two plates il fi', the former being bolted to the top of the side spring and the latter to the under side of the body-frame, so that the body rests upon it. The plate t" carries the pivot-pin 2, which projects outwardly and engages into a socket formed on the plate z'. This socket has a bushing i3 of rubber or other like material, causing friction which surrounds the pivotpin and is compressed around it by a screw @"4 and washer all in such manner as to increase the friction of the pivot. The plate t' on the side which supports the engine-shaft is formed with a forwardly-extending bracketi5, in which the bearing g for the engine-shaft is formed.

The front end of the body is supported upon a double elliptical spring M, which carries the steering-post j, to which the steeringhandlej is pivotally secured.

The bodyL is supported upon the spring M through the medium of a guide-bearingjz, secured at the lower front edge of the body and restingupon a shoulderj3 of the steeringpost. The lower portion of the spring M is connected to the front axle in the axis of the steering-post in the following manner: A block 7c, sleeved upon the front axle, is held in place thereon against lateral displacement by two split clamping-collars 7a', united by a cross-bar Zas. The block 7c is formed with a flat bearing on top, upon which the spring M is supported by means of two clamping-plates 7a2 k3, (see Figs. 5 and 7,) the lower one of which is formed with a pivot-pin Zt", which turns loosely in a hole 71:5 in the block 7c and bears a nut at its lower end, while the upper plate 7a2 is formed with a rearwardly-projecting arm k6, to which the connecting-rods 707 of the steering mechanism are pivotally secured.

The ends of the side springs are secured to the front axle by clips N, (shown in detail in Figs. 9 and 11,) in which Z is a split clampingcollar formed on top with a bearing-plate Z' for the spring to rest on, and Z2 is a clamping cap-piece extending over the extreme end of the spring and provided with a depending rear flange Z3, forming a stop for the end of the spring. The cap, spring, and bearingplate are provided with coincident holes, through which a clamping-bolt Z4 passes to connect the parts together. The clampingpiece is also formed with two side bars Z5 and a cross-bar Z", uniting the side bars in such manner that the side bars bear upon the top of the axle, and thereby press the cross-bar against the under side of the bearing-plate. The rear ends of the side springs are secured to .the rear axle by similar clips N', except that instead of the bolt Z4 the cap-piece is se cured by a U -shaped bolt Z7, which passes beneath the bearing-plate Z', and with the addition of a set-screw Z8, which passes through the cross-bar ZG and bears against the huh of the clam ping-collar. In this machine the rear clips permit adjustment of the rear axle for the purpose of tightening the drive-chain.r

The parts being constructed and arranged as shown and described, they are intended to accomplish the following results:

First. In supporting the motor in the manner described it will be seen that perfect facility is afforded for its accurate ali'nement. The cross bars .I J', being independently clamped to the side bars, can be adjusted jointly or independently forward or backward and at the same time the motor-frame can be laterally adjusted upon the bars in any way that may be necessary to a perfect adjustment. In making the motor-frame a direct structural part of the running-gear I obtain sufficient rigidity without adding the weight of a separate frame and at the same time avoid the disadvantage of an absolutely rigid supporting frame, which on uneven ground would not allow the weight to be brought on all four wheels.

Second. Itis well known that all reciprocating engines, especiallygas and vapor engines, if supported upon springs produce a teetering motion which if the engine is supported upon the side springs causes an alternate deflection in the spring-arms-that is to say, as one end goes up the other goes down. There is therefore a central point in each spring which does not partake of this motion, and at this point, which is located between the points at which the cross-bars .I J are connected, I support the body upon each side spring, providing for the necessary balance to maintain the body by supporting it additionally upon the front axle, which is not affected by the engine motion. In this manner the body is not only supported upon the side springs entirely independent of the motor and its supports, but also free from the jar and vibrations caused by the movement of the engine, which makes the vehicle easy and pleasant to ride without the use of separate springs intended to counteract the engine motion. By the use of the friction-bushings in the side bearings the wear upon the pivots is reduced and the rocking motion of the body is checked.

Third. The clips N clamp the springs l only at their extreme outer ends. The whole IOO IIO

length of the springs are therefore rendered effective. At the same time they have a bearing upon the Whole bearing-plate Z by reason of the cappieces, Which by giving them a bearing upon the axle press the cross-bar Z6 of the cap-piece against the under side of the bearing-plate Z by the clamping force of the bolt against the other end, thus virtually inaking it the equal of another bolt. The clip N permits the usual adjustment of the rear axle for tightening the chain, and it Will be noticed that in addition to the other advantages which the clip N has it has the set-screw ZS on theV inside under the spring, where it is less liable to tear the clothing or be broken on'.

Fourth. The connection betvveen the spring Maud the front axle is made through `the block 7c, which is sleeved upon the front axle.

Thus if the ,front axle is v.slightly turned, as

it will be by the motion of the side springs, it

` will have no effect upon the steering-rod,

which if .the block were fast upon theaxle would cause it to bind. .At the same time the spring M still bears upon the top of the axle and lhas no tendency toturn the block and cause a binding of the pivot-pin 104. By this construction the steering-gear is free from allstrain and not subject to undue Wear, and at the same time'the frontend of the body is freelyl supported upon the springM, and any undue vibration upon vthe body .through thisspring is counteractedv by inrigidly connected, of transverse rodssup ported upon said side springs at corresponding points intermediatetheir length and having their ends secured thereto independently of'each other, the motor supported upon said transverse rods independently of the side springs and thebody supported upon thesidesprings independently of the motor.
